This was a banner year for science fiction and fantasy books
— and choosing the year's best titles was harder than usual. From
time-slashing serial killers to grand space operas to Kafka-esque nightmares,
this was a year of brilliant reads. Here are the 20 best science fiction and
fantasy books of 2013.

Neptune's Brood by Charles
Stross

The perfect book for the strange economic daymare we've all been trapped in for the past five years — with Neptune's Brood, Stross turns his searing curiosity onto the murky realm of bankers.

A stand-alone follow-up to his Saturn's Children,
this novel sees a posthuman historian of accountancy practices, Krina
Alizond-114, searching for her missing cousin while trying to figure out
why so many people want her dead. But the real thrills in this novel
come from Stross' wily speculations about interstellar economics — you
can see why this was Paul Krugman's favorite book ever.

This
time around, James Holden and his crew are investigating the alien
artifact discovered out beyond Neptune's orbit — only to discover
they're the target of a new conspiracy. With each installment, you
wonder how Abraham and Franck will manage to top themselves — and they
keep doing it.

NOS4A2 by Joe Hill

Hill channels the classic novels of his dad, Stephen King, with this story
about another one of those serial killers who travels through uncanny
realms and preys on special children. The one child who got away from
Charles Talent Max, a girl named Vic, grows up to find that Manx has
taken her son — and the creepiness just starts there.

Republic of Thieves by Scott Lynch

Lynch's long-awaited new novel about
that charming bastard, Locke Lamora, doesn't disappoint in the
slightest — everything you loved about that rogue is back in full
force, even as Lamora is in worse straits than ever before.

Poisoned
and in dire straits, Lamora needs all his cunning to survive — and
meanwhile, we finally meet the mysterious woman from his past, Sabetha,
who fully lives up to our anticipation.

Love Minus Eighty by Will McIntosh

Based on his Hugo-winning short story "Bridesicles," McIntosh's newest novel turns
an ultra-creepy premise (rich men defrost cryogenically frozen dead
girls for "dates" or marriage) into a surprisingly charming cross
between Philip K. Dick and Jane Austen.

From the lesbian who finds
herself accidentally frozen in a heterosexual dating center to the
dating coach who helps the woman who's stealing the man she loves,
McIntosh shows how love is never easy — even if technology lets you
revive the dead and live virtually forever.

Aliens: Recent Encounters, edited by Alex Dally MacFarland

There were a lot of anthologies this year, including several with ambitious themes — but this one blew us away more than any other.

Mostly
because of the sheer volume of greatness contained in these 32 stories,
ranging from Ken Liu's "Bookmaking Habits of Select Species" to Ursula
K. Le Guin's "Seasons of the Ansarac." These are classic stories of
alien encounters, from some of the best science fiction writers working
today.

The Accursed by Joyce Carol Oates

At last, Oates completes a novel she left unfinished for years — a capstone to her string of gothic novels. And this one's a doozy.

A historical fantasy that includes real-life figures like Mark Twain and Woodrow Wilson, The Accursed
is a taut supernatural mystery about an ageless figure who abducts a
young woman on the brink of getting married, and the man who tries to
get her back. A sly, subversive look at repression and class divisions
at the turn of the 20th century.

Tidhar made a splash with his daring, off-kilter novel Osama,
but this time around he's delving into the horrors of the twentieth
century with a story of intrigue that blends spy drama with superheroic
thrills — and even if you think you've seen everything in the
superheroic realm, Tidhar will prove you wrong.

The Golem and the Jinni by Helen Wecker

Here's another fantastical novel
that takes place at the turn of the 20th century — but this time
featuring a meeting of supernatural beings from Jewish and Arab
mythology.

A golem named Chava survives the death at sea of the
rabbi who created her and arrives in New York in 1899, where she meets
Ahmad, a jinni who was born in ancient Syria — and the two of them form
an unlikely bond. This book appears to be a simple fairy tale at
first, but it raises serious philosophical questions and explores the
clash of cultures in the New World.

We Are All Completely Beside Ourselves by Karen Joy Fowler

Like Gaiman's Ocean, this is another book about probing buried memories, and dealing with the mysterious, tricky space of childhood.

But
the protagonist of Fowler's novel has a very different sort of
childhood to explore, one in which she was part of a strange science
experiment that has left strange traces in her life. Even as Fowler keeps reminding us how unreliable our memories are, she builds a jarring image of Rosemary's bizarre experiences.

Nicola's
effortlessly immersive descriptions of life in the Middle Ages will
enthrall you, but so will her depiction of a woman trying to survive as
the Seer in a society that believes in prophecy and conflicting gods. A
must-read for anybody who writes (or reads) historical fantasy.

Something More Than Night by Ian Tregillis

A noir pulp detective novel set
in the classical vision of Heaven, featuring angels, cherubim and the
Voice of God — it could have been a genre pastiche, more concerned with
being amusingly self-referential than actually engaging.

Instead, it's a masterwork with more layers than you realize at first.
Tregillis uses his genre tropes as a way to show how we reconstruct
reality according to the stories in our heads — and you see how this
could be a problem when you're dealing with immortal beings and cosmic
mysteries. Still not sure how I feel about the final twist in this book,
but I love it overall.

Life After Life by Kate Atkinson

This novel took the book world by storm earlier this year, and it's easy to see why — it's like The Time Traveler's Wife, except with a healthy dose of Downton Abbey. But it's even better than that makes it sound.

Ursula
Todd dies as a baby in 1910 — but then her life restarts, and this
time she lives. She dies again, and again, but each time her life is
rewritten so that she lives, and we see different alternate paths that
her life could have taken. The result is a fascinating look at tragedies
that might have been, and the way that history always sweeps us
forward.

The Best of All Possible Worlds by Karen Lord

Even in a year of weird books, this is an odd one
— it starts with a massive genocide, with the homeworld of the Sadiri
being wiped out in a brutal attack. And then it turns into a light
romantic comedy, as the last surviving men of the Sadiri race try to
find brides to mate with.

Yes, it's Seven Brides for Seven Post-Apocalyptic Brothers. But
at the same time, Lord takes you through the Sadiri diaspora on another
planet, and we see how the Sadiri culture has changed as a result of
being scattered.

Tenth of December by George Saunders

These
days, everybody is channeling Franz Kafka, and we've lost count of the
jarring short stories about bewildering transformations and confounding
officialdom that we've read. But with this book, George Saunders shows us what being dwarfed by an unforgiving world is really all about.

As
usual, Saunders' protagonists are trapped in a world they can't
control, and with these stories he gets further into the heart of our
complicity with evil, and our capacity for self-deception. The real surprise here is how much compassion Saunders has for his ruinous characters.

MaddAdam by Margaret Atwood

The trilogy that began with Oryx and Crakeconcludes, and the series ends in a startling, fascinating way that confirms this as a major work.

This time around, she finishes tearing down the world that Big Science made — and gives us a surprising glimpse of hope. The trilogy emerges as a techno-realist story of humanity's self-destruction, but also our redemption.

Ancillary Justice by Ann Leckie

This list isn't strictly a countdown — but Ancillary Justiceis definitely our #1 pick of the year's best science fiction or fantasy book.
